' These machines compriseas ya rule a rotary carrier upon which are mounted in circular series a plurality of beating elements which are loosely hung and capable ofV yielding inwardly against the action of centrifugal torce while themaehine isinV motion. Vith this rotating poundingup drum cooperates 'a side beater which is reciprocated in a path sub-` stantially vertical tothe axis of the drunn The work is presented hitherto to the beating tools 'by khand although some abutmentV or supporting-means for the shoe are generally used.` This is very harmful to the attendant inasmuch as the vibrations ofthe toolsare transmitted to his arms.

It is the primary objectr of the present *inl vention to so construct the pounding-upvma y chine as to fully relieve the operator. The principal feature of the invention consists in means provided for supporting and automatically guiding the shoewhile itis oper- Yated upon bythe beating tools. *Otherfea tures of the invention including certain details ot' construction and combinations of parts, will be more fully explained in the accompanying description and will then be pointed out in the claims.

The machine-frame consists of three parts 1, 2 and 3. The part 1 accommodates the means for driving the beating tools and for moving the shoe-jack. The part 2 forms the support for the shoe-j ackand carries the part 3. In the fpart' Bthere are `joui-nailed ,the pounding-'up drum 11 andV the sidebe'altingr'l tool 66. L

The tools n the beltor chain 9,the intermediate shaft 6,'

thepulley 6', thebelt'lO, the pulleyt 85 and'y the shaft 7. Tot'he "shaftl7lis fastened `the pounding-up drum yl1. The side-wallsfllf ofthe drum arelconnected bolts 11 carrying the beating rings llff. When the drum is rotating they rings 11" are thrown tout# Wardly bycent'rifugal force and are* free" tof yield when coming into contactwith the'shoe operatedl upon. The diameter ofthe rings grows bigger from' `the sides r"to fthe.'l middle shaft73`, the middle partof which Yhasthe shape of a triangular cam 69` This cam'rotates within the'ca'sing 69 Y fastened t0 the vare drivenY by the main :shaft 4;

with their front-ends against the "saidjarms and with their rear ends against the member 1 76 pivoted at75 in the head 3. The tension of the springsl74.- is regulated by the screw spinf dle 77 which may be rotated by the hand- The 4rotationof the shaft73 isderived from the shaft 7 by means yof thel sprocket wheels 70, 72:' andwof the sprocketK chain 71. The cam 69A imparts the'movement i to the beating tool `66. The arms 67, 68' aref with the crank-arm '81"of the hand-leven 81.?A

' The lever 81 may-be swung on the shaft 7 and l be arrested in the position desired by the engagement of the ratchet 85 of the lever 86 into the teeth 87 of the head 3. By so adjusting the lever 81 the weight 80 may be brought along the line 84. more or less. into alignment with the beating-direction of thesidepounding member 66 to more or less counteract the blows of the beating member 66.

The shoe-jack consists of a toe" support 6.1 and a heel-support' 6:1 arranged on a plate. 62. By means of the hand-.wheel 64 having'. a wedge-part 65thel height of the heel-support may be adjusted. The platev 62 is aecommodatedin the housingA 60 upon a pneumatic tire '63 or upon springs. rhe housing 60. is adapted to slide n the head-plate 53 of the hollowl vertical shaft 52. The vertical position of the shaft 52 can be adjusted by means of the screw threads. 56. andthe hand wheel 5.4 by meansof the ball bearing 55:

upon thesleeve 5.0. The sleeve 59. is threaded intol the bushing 51 ixedin the part. 2. To the lower end of the sleeve 5.0 is fastened thel toothed wheel 31. which is. in. mesh with the toothed segment 28. Tothe lower end of the hollow shaft 52 is fastened the toothed Wheel 32l in mesh withrthe toothed segment 29.. 'W'ithinz the hollow shaft v52v is. accom.-

modated the. shaft.` 57A to the lower end ofy which is .fastened the toothed .wheel 33 in mesh with the, toothedsegment v.To the tatable on theiixed shaft 27 and'their rearV parts 34',v 35, 36. are. vconnected by intermediate adjusting; members andthe links 37, 43, 44 respectively with the levers 24, 25, 26' rotatable uponthe shaft 20. Xed in the, framepart 1.y The intermediate `adjusting mem.V bers connecting the vpart 34 with the link. 37

consist of. the; lever pivoted at-.40. to the part 34 and of .the notched segment39-swing ing, about the shaft 38. The lever 40passes through the slot 41 of the segment and its position relatively to the latter may be adjusted by engaging the. snap 42..into any of the notches 39', see Fiff. 2.. In a similar way the Apart 36 of the. toothed segment 30l is. connected to the link 44 by the lever 46 and the notched segment 45, the snap 48 of the lever 46 engaging into the notches 45 of the segment 45, see Fig. 3. The connection of the part 35 with the leverv 25 is: not shown as it. i-sidentical'. with the connections .just descri-bed.. Y

. 'Ashaft 14 suitably journaled inthe fijamei part 1 carries the worm gear 13,. and the discsy 15 and 16. The worm gear 13 is driven by the worm V12in-tegralwith the shaft 4 and isrprovided 'on its underside with a camgroove 17 into" whichengages the roll 21 of the leve-r 24 mentioned above. The disc 1.5 hasan upper cam-groove18 and a. lower canigroove 19. Into the upper cam-groove 18 engages the roller 22' of the lever 25 and into the lower groove engages the roller 23 of the lever 26. By the means described the lever 24 rotates the toothed gear 31. and the threaded sleeve to lift the head plate 53 with the shoe jack 61, 61. The lever 25 rotates the gear 32 in order to rotate the head plate 53 and'` the shoe `iack. rlhe lever 26 rota-tes the gear 33m order to move the housing 60 horizontally against and from the beati-ng tools. The three levers 24, 25, 26 swing in time relation in order to adapt the path of the shoe tothe curvature of the outline of the latter. In the case of changes of the shape and the size of the shoe the adjustments described in connection with Figs. 2 and 3 may be made use y freely on the shaft 4. The coupling-part 116 Y isslidable on the shaft 4 but is prevented from rotating thereon by the key 4". The spring4 111 fastened at 111 tothe frame-part 2 and at 111 to the lever 113 tends to keep the coupling parts in engagement. i But these parts can be disengaged by the lever 113 pivoted on the bolt 112. The lever 113 hasrollers 113 projecting into a. circumferential groove of the hub 114 of the coupling-part 110. The

lower` end of the lever 113 is pivoted tothe bar 116 the free end of which is supported by the knee-lever 1.25 pivoted tothe fra-me 1 at 126. The lever 116 is provided on its under# side with a dog118 adapted to comeinto contact with a pin 119 of the rotating disc 16. Every time the bar 116 is pushed to the right of Fig. 7 by a pin 119 the coupling becomes disengaged and the machine stops. To bring the machiney into operation the free end of tbe lever 116 is brought out of reach of the pin 119 by depressing the treadle 120-pivoted on the bolt 121 and connected by the'link 124 with the said knee-lever 125. It the machine is to be stopped after every full rotation of the shaft 14. the disc 16 is provided-with one pin. 119 only, but if it is tobe stopped after every half of rotation the disc is provided' with two pins 119, 119.

part form with axis of rotation of the head plate 53 angles oi the same amplitude a.

lli/Then the treadle 120 is depressed the shoe is moved by the cam-groove 19 from the position A into the position B, the toe of the shoe .i

being first .worked upon at 1.01.v .The shoe is f then turned by the cam-groove 18 to the ri ht about the axis as seen from Fig. 4, so t at the toe is Worked upon at 102. The shoe is thereupon simultaneously slightly rotated by means of the groove 18, lowered by the groove 17, and moved underneath the drum 11, so that the part 102 and the part c of the edge are Worked upon, see Figs. 4 and 5.

The shoe is then brought back in the original position shown in full lines 4in Fig. 4, and the opposite edge of the shoe is Worked in a like manner. For pounding up of the heel-part the shoe is shifted into the position A, and after turning about 180o the shoe is moved back into reach of the beating tools. Instead of imparting to the shoe-j ack an oscillatory and rotating movement, in the manner just described it is of course possible to only rotate the 'shoe-jack in a continuous manner once around in order to poundup the toe and heel portions of the shoe.

The machine described may stop after every half of a revolution and can be used for pounding-up the'heel-portionof the shoe only. In this casethe Worin-wheel 13 and the disc 15 must be exchangeable as the camgrooves must have another configuration if the machine is to stopafter a halr` of a revolution. For stoppingl the machine after every halt of a. revolution a pin 119 is diagonally arranged to the pin 119.
